Definitions

  • Industrial systems that have the requisite alkaline pH and/or high hardness include, for example, cooling towers, paper mills, paint and paint films, cosmetics, and metalworking fluids.
  • n-decylthioethylamine can be applied to solid objects that are either in contact with aqueous systems or are themselves prone to algae attack due to high water or moisture content and the requisite exposure to light.
  • solid objects include, for example, wood or lumber, textiles or fabrics and plastics.
  • solvent composition containing the amine is usually applied per 1,000 square feet (1 to 100 liters/24.543 square meters) of surface to be treated.
  • sufficient composition is employed adequately to impregnate the wood.
  • the inoculation with bacteria was accomplished using the following procedure. Twenty-four hour cultures of the bacteria were prepared by incubating the bacteria in tubes containing nutrient broth for 24 hours at 30°C in a shaker. Dilutions of the 24 hour culture were made so that a suspension was made, containing about 108 colony forming units (CFU) per ml of suspension of bacteria. Aliquots of 0.3 ml of the above suspension were used to fill individual wells of a Steer's Replicator. The Steer's Replicator was then used to inoculate the petri plates.
  • CFU colony forming units
  • the petri plates were incubated at 30°C for 48 hours and then read to determine if the test compound which was incorporated into the agar prevented growth of the respective bacteria.
  • the minimum inhibitory concentration (MIC) for each bacteria was defined as the lowest concentration of the test compound which prevented growth of that bacteria.
  • Hard water was prepared by sterilizing deionized water and adjusted to 500 ppm hardness and 100 ppm alkalinity by addition of 16.7 ml of sterile CaCl2 ⁇ 2H2O (36.8 g/l), 16.7 ml of sterile MgSO4 ⁇ 7H2O (12 g/l), and 5 ml of sterile NaHCO3 (16.8 g/l) to 1 liter of water. The pH was adjusted by addition of diluted NaOH or acetic acid.
  • TOC total organic carbon
  • TDS ppm total dissolved solids
  • Enterobacter aerogenes ATCC #13048
  • ATCC #13048 Enterobacter aerogenes , ATCC #13048
  • Three 0.1 ml aliquots of a 24 hour nutrient broth culture were pipetted onto three nutrient agar plates and spread uniformly with a Petri dish spreader. After 24 hours' growth, the cells were scraped and washed off the agar surface with sterile glass rods (hockey sticks) and sterile saline solution. After vigorous mixing (vortexing) to break up clumps, the cell suspension was filtered through a sterile filter (Whatman #4) to remove residual clumps.
  • the resultant cell suspension was subsequently diluted with sterile saline to give 1:100 dilutions which resulted in an optical density (O.D.) at 550 nanometers (nm) of 0.06 (Bausch & Lomb Spectronic 710 equipped with a flow thru cell). Solutions with this optical density, when diluted 1:100, contained approximately 1010 CFU/ml when plated on standard nutrient agar. The exact number of organisms was determined by making serial dilutions of the cell suspension and plating them on nutrient agar plates. Each of the serial dilution tubes was also streaked on a nutrient agar plate. These streaks of known concentrations of organisms were then used as controls to determine the number of organisms in the test samples.
